Description

Technical Field

[0001] The utility model relates to the field of crushing and screening machines, and specifically relates to a roll-type crushing and screening machine. Background Art

[0002] The roll-type crushing and screening machine is a commonly used mineral processing equipment. This machine is composed of an upper body, a frame, a reducer, a roll-type crusher, a motor, a shaking screen, a vibrating feeder, etc.

[0003] This equipment uses the rotation of the rolling rolls to crush the material blocks, and then screens them through a screening machine to separate materials of different sizes. It has the advantages of high crushing efficiency, low energy consumption, and convenient maintenance, and is widely used in industries such as coal, metallurgy, and building materials.

[0004] Currently, when the screening machine screens materials, the small-particle materials pass through the screen mesh, while the large-particle materials remain on the screen mesh. Once the materials accumulate, the screen mesh will be blocked, reducing the screening effect. At the same time, the existing screening machines have a single function and can only screen the crushed materials, with certain limitations in use. Therefore, it is necessary to make improvements and propose a roll-type crushing and screening machine. Content of the Utility Model

[0005] The purpose of the utility model is to provide a roll-type crushing and screening machine to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A roll-type crushing and screening machine, including a device main body, and the device main body includes:
